TROUBLESHOOTING & REPAIR
POSSIBLE
CAUSE
1. Verify the ground connection to
the power source is wired cor-
rectly.
2. See the power source service
Manual.
1. The system detected that one of
the voltage sense lead cables
was disconnected from the weld-
ing circuit during a weld.
1. The wire drive motor has over-
heated. Check that the electrode
slides easily through the gun and
cable.
1. The wire drive motor current
draw has exceeded limits, usually
because the motor is in a locked
rotor state. Check that motor can
turn freely when idle arm is open.
1. The drive motor in the spool gun
or push-pull gun is drawing too
much current.
1. The power source does not have
any welding programs loaded.
Required configuration could not
be found.

RECOMMENDED
COURSE OF ACTION
1. The main processor in the system
did not respond to another
processor within the allotted time.
Reflash system with latest soft-
ware. Replace circuit board.
Verfy that leads 67 and 21 is
enabled and connected. See
enhanced schematic.
2. Remove tight bends from the gun
and cable.
3. Check that the spindle brake is
not too tight.
4. Verify a high quality electrode is
being used.
5. Wait for the error to reset and the
motor to cool (approximately 1
minute).
2. Verify that the gears are free of
debris and dirt.
Check spool gun brake or feeding
for binding. Replace spool gun cir-
cuit board.
Make sure the status of all devices
is conected correctly to the machine.
Reflash system software.
